STU M P- EXTRACTOR.

SEEQIFICATION forming part of Letters Patent No. 318,810, dated May 26, 1885.

Application filed April id, 1885. (No model.)

To ttZZ whom it may concern:

Be it known that I, FRANK B. SMITH, a citizen of the United States, and a resident of Tomah, in the county of Monroe and State of WVisconsin, have invented certain new and useful Improvements in Stump- Extractors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which I Figure l is a perspective view showing my improved stump-extractor in position for operation. Fig. 2 is a vertical sectional view showing the winding-drum in position for operation. Fig. 3 is a perspective detail view of the lower collar or washer. Fig. 4 is a perspective detail view of the upper collar or washer, and Fig. 5 is a perspective detail view of the pulley-block used in connection with my invention.

The same letters refer to the same parts in all the figures.

This invention relates to stump-extractors; and it has for its object to provide a device of this class which shall possess superior ad vantages in point of simplicity, durability, and general efficiency, and in which many objections found in stuinpextractors of the same class, as now ordinarily made, shall be done away with.

With these ends in view the invention consists in the improved construction and arrangements of parts,which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates a winding-drum consisting of a cylindrical tube or barrel provided at its upper and.

lower edges with horizontallyextending flangesB B, the inner adjoining faces of which are provided at their outer edges with ridges 00, having flat polished faces and rounded edges, so as not to cut or chafe the rope D when the latter is being wound upon the drum. Said ridges serve to crowd the rope ed the outer coil in the act of winding, thus causing the rope to be wound upon the drum tightly and evenly.

The upper flange of the windingdrum is provided at its periphery with a hook, E, having a perforation, F, registering with a perforation, G, in the said flange. The end of the rope D is passed through the perforations G and F and knotted, as shown, and is thereby attached securely to the drum. The upper flange B is also provided with a laterally-extending lug or stud, H.

I designates the sweep or operating-lever, which in operation has its inner end adjusted .in the hook E, the body of said lever orsweep being connected with the stud H by an oblong link, J, which admits of sufflcient play to the said lever.

A lead pole, K, is connected in the usual manner to the sweep or lever.

The bearings for the winding drum are formed by a pair of collars, L and M, the lower one of which, L, is provided with an annular horizontal flange, N, at its lower edge, while the upper collar, M, has asimilar flange, 0, located about midway between its ends or edges. In practice the collar L is adjusted over the stump of a tree, as shown in the drawings atP. The drum A is then slipped over the stump, so as to rest upon the flange N of the collar L, and the collar M is finally slipped into position, as shown, and secured by means of a pin or bolt, Q, driven into or transversely through the stump. It will thus be seen that the stump forms at thesame time the axis and the anchor for the windingdrum, which latter revolves around the stump, which latter will therefore not interfere with the motion of the sweep or lever, which is a common objection in devices of this class where the frame in which the Windlass is journaled has to be anchored to a separate stump or post, which must be cut down. to such a height as to permit the sweep to pass over it. Simplicity of construction and inexpensiveness are also thus promoted.

The rope D, one end of which is attached, as described, to the winding-drum, passes over a pulley, It, and its other end is attached in any suitable manner to the stump or anchorpost. The block or clevis S of the pulley R is provided with a curved yoke, T, adjusted thereon, as shown, and serving to hold the rope in contact with the pulley and prevent it from dropping off when the draft is slacked. The

pulley-block is connected by a rope or chain, U,with the stumps to be pulled or trees which are to be uprooted, as clearly shown in Fig. 1

of the drawings.

'From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

The construction is simple and inexpensive, all frame-work being dispensed with. The operation is efficient, and the machine may be easily manipulated.

Having thus described in yinvention, I claim, and desire to secure by Letters Patent of the United States-- 1. In astump-extractor, a Windlass or winding-drum adapted to be adjusted upon and re-' volve around a tree-stump, substantially as herein described, for the purpose shown and specified.

2. In a stump-extractor, the combination of a Windlass or winding-drum having a cylindrical tubular barrel with flanged collars, adapted to form an axle for the same, substantially as herein described, for the purpose shown and specified.

8. In astump-extractor, the combination of a Windlass having a cylindrical tubular barrel and collars adapted to be adjusted upon a tree-stump, so as to form bearings for the said Windlass, the lower and upper collars being provided with annular horizontal flanges, respectively at the lower edge and at the middle, substantially as herein described, for the purpose set forth.

4. In a stumpextractor, the hereindescribed windlass or windingdrum having flanges at its upper and lower edges, said flanges being provided on their inner faces, near the edges, with annular ribs having smooth polished faces and rounded edges, substantially as herein described, for the purpose set.forth.

5. The Windlass or winding-drum consisting of a flanged tubular cylinder the upper flange of which is provided with a perforation, and a perforated hook registering therewith for the attachment of the rope, substantially as herein described, for the purpose set forth.

6. The windlass or winding-drum consisting of aflanged tubular cylinder the top flange of which is provided with a hook and with a laterally-extending stud, in combination with the sweep or operating-lever and a connectinglink, substantially as herein described, for the purpose set forth.

7. In a stump-extractor, adraft-pulley having a yoke adjusted upon its block or clevis,

and adapted to bear against the rope and hold it in contact with the rim of the pulley, substantially as herein described, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

FRANK B. SMITH.
